ʻIke laulā
ʻO ka mea hoʻokaʻawale mana 4-ala kahi mea maʻamau i hoʻohana ʻia i nā ʻōnaehana kamaʻilio uea ʻole, nona kahi kikowaena hoʻokomo hoʻokahi a me nā kikowaena hoʻopuka ʻehā.
ʻO ka hana o kahi mea hoʻokaʻawale mana 4-ala, ʻo ia ke kaʻana like ʻana i ka mana o ka hōʻailona hoʻokomo i nā awa hoʻopuka 4 a mālama i kahi lakio mana paʻa ma waena o lākou. I loko o nā ʻōnaehana kamaʻilio uea ʻole, hoʻohana pinepine ʻia kēlā mau mea hoʻokaʻawale mana e kaʻana like i nā hōʻailona antenna i nā modula hoʻokipa a hoʻouna paha he nui me ka mālama ʻana i ke kūpaʻa a me ke kaulike o ka hōʻailona.
Ma ke ʻano loea, hana pinepine ʻia nā mea hoʻokaʻawale mana 4-ala me ka hoʻohana ʻana i nā ʻāpana passive e like me nā laina microstrip, nā couplers, a i ʻole nā mea hoʻohuihui. Hiki i kēia mau ʻāpana ke hāʻawi pono i ka mana hōʻailona i nā awa hoʻopuka like ʻole a hōʻemi i ka hoʻopilikia like ʻana ma waena o nā hoʻopuka like ʻole. Eia kekahi, pono nō hoʻi ka mea hoʻokaʻawale mana e noʻonoʻo i ka laulā alapine, ka pohō hoʻokomo, ka hoʻokaʻawale ʻana, ka lakio nalu kū a me nā palena ʻē aʻe o ka hōʻailona e hōʻoia i ka hana a me ke kūpaʻa o ka ʻōnaehana.
Ma nā noi hana, hoʻohana nui ʻia nā mea hoʻokaʻawale mana 4-ala ma nā ʻano like ʻole e like me nā lako kamaʻilio, nā ʻōnaehana radar, ke kamaʻilio ukali, a me ka nānā ʻana i ka spectrum radio. Hāʻawi lākou i ka maʻalahi no ka hana ʻana i nā hōʻailona multi-channel, e ʻae ana i nā mea hana he nui e loaʻa a hoʻouna paha i nā hōʻailona i ka manawa like, e hoʻomaikaʻi ana i ka pono holoʻokoʻa a me ka hilinaʻi o ka ʻōnaehana.
